Weight Loss Glossary RRespiratory ChamberA room set up to measure energy expenditure. It is a airtight, thermally insulated living chamber. The heat produced by the person inside is removed by a stream of cold water through tubes near the ceiling of the chamber. Source:McArdle, Katch & Katch. (1985) Exercise Physiology, P. 121 Resting Metabolic RateYour resting metabolic rate is the energy used by your body at rest and makes up the majority of your energy expenditure. It is used interchangeably with basal metabolic rate, but is not the same. Obese individuals generally have a higher resting metabolic rate than do those of normal weight. Resting metabolism is also about 5 to 10% lower for women, because women generally have more body fat than men. The resting metabolic rate has been calculated as a function of the body's surface area. You can estimate your resting metabolic rate through the following formula's.McArdle, Katch & Katch (1985) give the following formula for calculating resting metabolism. kcal expenditure per hour (BMR) x surface area in square meters x 24 hours = kcal per day. The Harris-Benedict formula for men and women applies the resting metabolic rate and then assigns an activity factor. Women(655.1 + (9.56 x weight in kilograms) + (1.85 x height in centimeters) - (4.68 x age)} x 4.2 = kJ per day. Men(66.47 + (13.75 x weight in kilograms) + (5 x height in centimeters) - (6.76 x age)) x 4.2 = kJ per day. Source:McArdle, Katch & Katch. (1985) Exercise Physiology, p. 132 Noakes, M.
